...Yi Wang; Liang Gang; Shuo Liu; Yi Cui In this paper, a fretting damage model based on fractal theory is proposed. The Weierstrass–Mandelbrot function of fractal theory is used to represent the rough contact surface, and a corresponding contact parameter analysis method is also established. Based...

... surface is determined. The shape influence coefficient of the cylindrical contact is defined, and its rationality is evaluated. The influence of asperity distribution on the rough surface is determined, and the tangential contact stiffness macroanalysis model is constructed based on fractal theory...

.... Editor: Dong Zhu. 26 10 2012 24 08 2013 Based on contact fractal theory, a modified MB fractal model, and from the energy dissipation point and considering the mechanism of energy dissipation of joint interfaces, tangential damping and its dissipation factor models of joint...

... acquisition system was used to collect and analyze the experimental data of electrical contact resistance (ECR) and friction torque (T f ). Fractal theory was used to deal with the signals of the above two parameters simultaneously. The fractal dimension (D s ) and topothesy (G) of the signals were used...

... surface and opposing rigid plane In this paper, the above assumption is also made to establish the contact stiffness model based on fractal theory. To simplify the problem, the system of two opposing rough surfaces is replaced by a flat (smooth) rigid surface and a deformed rough countersurface...
